Knotter for harvesters.



Specification of Letters Patent. if

Application filed June 20. 1907. Serial No. 379,960.

To all whom it may concern:

Be it known that I, RICHARD H. MooRE, a

I citizen of the United States, residing at Wakita, in the county of Grant, Oklahoma, have invented a new and useful Knotter for Harvesters, of which the following is a specification. I

- This invention has relation to twine knotters'for harvesters and it consists in the novel construction and arrangement of its parts as hereinafter shown and escribed.

The. object of the invention is to provide a knotter having the usual number of parts employed in such a device but the improvement resides in the relative arrangement of parts and cooperation of the same, whereby,-all of I the grain is boundand tied'without the possibility ofhaving somevof the grain at times 'ass'ed from the harvester without being undled.

The peculiar arrangement. of parts and configuration of the same is such that the ends of the twine are positively retalned by the knotter until the oop in the twine has been passed around the same, thereby, assuring that the knot will be formed when the bundle is ejected from the harvester. The parts are also arranged so that the tying may take place close to the bundle and that the tension of the twine may be augmented around the bundle without affecting the tension of that part of the twine passing around the-needle,- thus; preventing the possibility of the grain slipping longitudinally from under the band oftlie twine after the bundle is bound thereby. The specific arrangement of the parts will be more definitely pointed out hereinafter. a

In the accompanying drawing :Figure 1 is a side elevation of the knotter with parts in section. Fig. 2 is a front'elevation of the same. Fig: 3 -1s a horizontal section out on the line 3 3 of Fig. 1. Fig. 4 is a bottom plan view of a portion of the knotter, and Fig. 5 is a transverse sectional view of the knotter out on the line 55 of Fig. 1.

The knotter comprises the spindle 1 to th end of which is fashioned a relatively fixed jaw 2'. Said jaw 2 is slightly curved laterally and its upper and lower surfaces taper graduall toward each, other. The jaw 2 is provide with the longitudinal channel 3 which is straight and of uniform transverse dimensions throughout. The said jaw is also provided with a circular erforation 4 located at the outer portion of t e channel 3.

The jaw 5 is pivoted to the jaw 2 inthe usual manner. The jaw 5 is adapted to enter the channel 3 of the jaw 2. The'outer end of the jaw 5 terminates short of the outer end of the jaw 2. The jaw 5 is provided. at its outer extremity with a hook portion 6 which Patented Dec. 10, 1907.

is disposed at a right angle to the longitudinal axis of the said jaw 5. The hook portion 6 is preferably rectangular in cross section and is adapted to enter the circular perforation 4 of the jaw 2 when the jaws 2'and 5 are closed together.

cally and horizontally from its intermediate portion to the hook portion 6 and the under side 7 of the said jaw-lies in a lane which is disposed at an acute an le to t e plane of the inner side 8- of the hook 6.

When the ewe are closed together the outer portion 0 the.

side 7 of the aw 5 comes in contact with the bottom of the channel 3 while the inner portion of the side 7 remains out of contact with the bottom of the said channel.

From the foregoing description it will be seen that a knotter, having the usual number of parts, the portions of which are novelly disposed toward each other, is provided.

The advantage gained by the specific configuration of the parts is that by reason of the fact that when the jaws 2 and 5 are closed the side 7 of the jaw5 is inclined at an angle to the bottom of the channel 3 and the ends of the twine will be securel retained even though one end of the twine e thick and the The jaw I 5 gradually decreases in transverse dimensions both verti,

other endbe thin as the wedge-she ed dis- 1 position of the opposite surfaces of t e jaws will retain the twine. relative dis osition of the sides 7 and 8 it is impossible or the ends of the twine to slip Also by reason of the from the knotter before the loop of the twine is passed over the same. Also by reason of the fact that the perforation 4 extends all the way through the jaw 2 and is circular while the hook 6 is non-ciroular it is impossible for the said perforations to become-filled with "tar, oil, grease, etc, from the twine to such thatof the perforation 4 the said hook will' i not stick or wedge in the said perforation. By reason of the fact that the twine engaging end of the jaw 5 is shorter than thetwlne. en-

gaging end of thejaws 2 the ends of the twine may be retained between the said jaws while the loop passes from. the same and is immediately drawn taut around the ends of the twine while'they are still confined, thus tying the knot close to the bundle and augmenting the tension about the bundle. The feature last above described is of importance in the 'last invention in that in similar devices heretofore employing a hook or its equivalent" the jaw carrying the hook has been extended beyond the hook which necessarily requires the formation of a relatively large loop at the oint of tying and as the slack is taken up om this loop it is transmitted to the ortion of the twine passing around the grain and in some instances the ex ansion of thegrain is npt suflicient to ta e up this additional slack in the binding twine and the bundle 4 falls apart as it is deposited on the ground.

Having described. my invention what I claim as new and desire to secure by Letters- Patent is 1. A knottercoinprising a spindle, a jaw fixed thereto and havi-nga channel and a perforation entering the channel and located in the vicinity of the end of the jaw, a aw pivoted to the first said jaw and adapted to' enter said channel, the twine engaging end of the pivoted jaw being shorter than the of the pivoted jaw being shorter than the.

twine engaging end of the fixed jaw, said pivoted jaw having at the extremity of its end a hook adapted to enter said perforation, said pivoted jaw when closed having contact with the bottom of the channel at one point only which point is located between said hook and the pivot of said pivoted jaw.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
